All comments are stored in pg_description\n\nTo get the comments on a table, you need to join it to pg_class\n\nAs an alternative you can also use the function obj_description() to retrieve this information:\n\nSELECT obj_description(oid)\nFROM pg_class\nWHERE relkind = 'r'\n\n\nEdit\n\nIn psql you can simply use the \\d+ command to show all tables including their comments. Or use the \\dd command to show all comments in the system",
